The invention discloses a mineral dressing method for improving concentrate grade in a scheelite concentrating process. The mineral dressing method comprises the following steps: roughing scheelite raw ores to obtain scheelite concentrate; stirring and pulping the obtained scheelite concentrate, a stirring medium and a concentration regulator to carry out concentration, thereby obtaining scheelite concentrate and tailings; and carrying out magnetic separation on the tailings, returning the magnetically-separated concentrate to a concentrating and pulping process of scheelite raw ores and concentrate as a stirring medium. According to the mineral dressing method, a special magnetic garnet stirring medium is added into concentrating and pulping operation of the scheelite, so that crushing of calcium-containing ore flocs in ore pulp is realized, and therefore, the scheelite is separated from other calcium-containing gangue minerals, and the grade of the scheelite concentrate is improved.
